Cd(II) Adsorption Data for Pristine and Activated Bamboo Biochar

A study by H. Lalhruaitluanga investigates the adsorption of cadmium ions from aqueous solution using biochar derived from Melocanna baccifera bamboo. The dataset includes equilibrium and kinetic analyses, reporting maximum adsorption capacities of 15.15 mg/g for pristine biochar and 24.39 mg/g for KOH-activated biochar. The data was last updated on April 20, 2026.

Use Cases

• Modeling adsorption isotherms based on Langmuir and Pseudo-second-order kinetic parameters described in the study
• Comparing the performance of chemically activated versus pristine biochar adsorbents for cadmium removal
• Analyzing the influence of pH and activation methods on adsorption efficiency as detailed in the batch experiments
• Investigating surface complexation and ion exchange mechanisms suggested by FTIR spectroscopy results

Strengths

• Reports specific adsorption capacities: 15.15 mg/g for pristine and 24.39 mg/g for activated biochar
• Includes analysis of multiple activation methods (KOH and H3PO4) and identifies optimal conditions (60% KOH)
• Provides mechanistic insights from FTIR spectroscopy and kinetic models
• Released under a permissive CC-BY-4.0 license

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• The dataset is very small (15.8 KB), indicating limited scope
